Title: Arrangement for the temporary locking of a spindle against rotation
IPC: A47K10/28
Filed: 1970-06-09
Abstract: 1307410 Towel dispensers CWS APPARATE AG 9 June 1970 [24 June 1969] 27760/70 Heading A4G [Also in DivisionF2] An arrangement, for example for a hand towel dispenser, for the temporary locking of a spindle 1 against rotation after two or more rotations of the same comprises a member 5 which is movable relatively to the spindle against spring and/or gravity biasing and carries a suction cup 12. A campiece 8 is secured to the spindle and cooperates at every revolution of the spindle with a different one of a plurality of abutments to urge the member 5 and hence the suction cup 12 stepwise towards a fixed counter element 3. When the suction cup 12 and the counter element 3 are engaged the rotation of the spindle is halted by the engagement of the campiece 8 with the member 5 Fig.4, (not shown). The number of abutments equals the number of revolution required before locking of the shaft, the abutment except for the last engaged by the campiece 8 each comprising a pawl 7 which co-operates with a detent 11 fixed with respect to the spindle to hold the member 5 in sequence its intermediate position(s). As the or each pawl leaves the detent 11 it pivots under gravity and the reaction of a surface 10 into its initial position so that, when the suction cup 12 parts from the counter element 3 the member 5 can move under the spring and/or gravity biasing into its initial position. In a modification the cup carrying member is pivoted and the or each pawl is pivoted thereto Figs.5 to 8, (not shown). The spindle may be locked after one revolution by retaining the member in an intermediate position by a pin Fig.3, (not shown) or a pawl member Figs.5, 7, 8, (not shown).

Title: Improvements in fade-out shutter mechanism for cinematographic cameras
IPC: G03B15/08
Filed: 1933-10-09
Abstract: 412,815. Kinematograph cameras. VINTEN, W. C., c/o Vinten, Ltd., W., North Circular Road, Cricklewood, and SADLER, W. J., 208, Princes Avenue, Kingsbury, both in London. Oct. 9, 1933, No. 27787. [Class 97 (i).] In shutters comprising relativelyrotatable coaxial blades, the blades are adjustable by hand to vary the working aperture, and are relatively movable continuously, for fade-out or fade-in, by means operated positively from the camera mechanism, at a speed which varies in accordance with the working aperture and is such that fade-out &c. always occupies the same film length. As shown, shutter blades 1, 3 are respectively carried by a tubular shaft 2 and a shaft 4 enclosed thereby. The shafts are connected by a pin 5 projecting from the shaft 4, through a circumferential slot 6 in the shaft 2, into a helical slot 7 in a sleeve 8 slidable, but not rotatable, on the shaft 2, and are driven by a helical gear 13 from the main shaft of the apparatus. Axial movements of the sleeve 8 varies the relative position of the blades and the working aperture, and is effected by a sleeve 11 slidable in a fixed tube 12 and connected to the sleeve 8 by a ball thrust bearing 10. The sleeve 11 carries an inclined arm 15 having a slot 16 engaging a pin 17 on a link 21 pivoted to a slide 18 movable vertically by a hand knob 20 and rack-and-pinion. The pin 17 also engages a slot 28 in a lever 22 pivoted at 23 and connected by a link 25 to a crank 26 which may be rotated half a turn when coupled to the camera mechanism by operation of a fading control button. During normal exposure, the lever 22 occupies the position shown in Figs. 1 and 3 ; rotation of the knob 20 then raises or lowers the pin 17 in the inclined slot 28 between the extreme positions shown, and the resultant movement of the sleeve 11 moves the sleeve 8 and varies the working aperture of the shutter. When the pin 17 is in its uppermost position, Fig. 3, the aperture is a maximum, and when in its lowermost position, Fig. 1, the aperture is closed ; a scale in conjunction with the knob 20 indicates the size of the aperture. Movement of the lever 22 by the camera mechanism is effected at an angular speed which is unaffected by the position of the pin 17 in the slot 28, with the result that movement of the pin thereby, and consequently of the sleeve 8, always occupies the same time irrespective of the size of the working aperture of the shutter. Means for opening the shutter by hand after fade-out,and without running the camera, may be provided. A wheel 14 on the shaft 2 drives the intermittent mechanism.

Title: A circuit for the generation of a deflecting voltage for the time-base deflection of an oscilloscope
Inventor: LIST HANS
IPC: G01L23/26
Filed: 1969-06-03
Abstract: 1,273,001. Cathode-ray tube circuits; sawtooth generators. H. LIST. 3 June, 1969 [18 April, 1969], No. 27968/69. Headings H3T and H4T. A sawtooth time-base deflection waveform of constant maximum amplitude independent of variations in repetition frequency is produced by controlling the charging rate of the RC network in the sawtooth generator as a function of repetition frequency. The invention is described in connection with the production of the timebase deflection waveform for an oscilloscope used for displaying operating characteristics of an engine synchronizing pulses being derived from signals produced by a sensor responsive to the operational speed of the engine. As shown in Fig. 2, pulses I (see also Fig. 5) derived from the speed sensor 5 are supplied to a circuit 1 comprising, as shown in Fig. 3, a Schmitt trigger 101 producing the synchronizing pulses II employed to trigger the sawtooth generator 3 the pulses being also supplied to a monostable circuit 102 producing the waveform III (Fig. 5) the "mark" portions of which have a constant duration t 3  whilst the duration of the "space" portions varies inversely as the repetition frequency of the synchronizing pulses. The waveform III is then supplied to an integrator (e.g. a capacitor) 103 from which a D.C. voltage IV having an amplitude proportioned to the repetition frequency of the synchronizing pulses is derived. This voltage is supplied to a circuit 2 (termed a "variable attenuator") comprising, as shown in Fig. 3 a differential operational amplifier 201 the output of which supplies the charging voltage for the capacitor in the RC circuit of the sawtooth wave generator 3. Thus the amplitude V S  (Fig. 5) of the resulting sawtooth wave V is constant and independent of the repetition rate of the synchronizing i.e. is independent of the speed of the engine. The sawtooth wave generator may comprise a "Bootstrap" circuit as shown in Fig. 4 or a Miller integrator in which the R component is provided by a transistor the resistance of which is controlled by the D.C. voltage IV. To improve the linearity of the sawtooth, a circuit 4 (Fig. 2) comprising a differentiator and a further differential amplifier (Fig. 6, not shown) supplies a feedback quantity in series with the reference feedback between the potential divider 202, 203 and the input 7 of amplifier 201 (Fig. 3).

IPC: H01L21/00
Filed: 1968-06-12
Abstract: 1,269,634. Semi-conductor devices. NATIONAL RESEARCH DEVELOPMENT CORP. 10 June, 1969 [12 June, 1968], No. 28027/68. Heading H1K. A radiation detector comprises a slab of semi-conductor material having a PIN structure and having slots dividing opposite major faces into parallel ribs, the ribs on one face extending transverse to those on the other face, each slot extending to such a depth that it intersects the junction between the respective P- or N- type region and the I-type region. As shown, Fig. 1, a wafer 1 of P-type Ge doped with Ga has a series of parallel slots 5 sawn in one face to form ribs 3 and is etched and ultrasonically cleaned to remove damaged material. A lithium-in-oil suspension is applied to the unslotted face of the wafer which is then heated to diffuse-in the lithium to form an N- type region with an N+ -type surface layer. The PN junction formed is reverse biased to cause the lithium ions to drift-in to form an I- type region 6 between the P- and N-type regions. Slots 4 extending at right angles to the slots 5 are then sawn in the upper face of the wafer to form ribs 2. The wafer is then etched and quenched in an aqueous solution of CaCl 2 , these steps being performed in such a manner that both sides of the wafer are exposed to the fluids. This may be achieved by using a stoppered funnel, Fig. 3 (not shown), or by supporting and rotating the wafer in the etch by means of a nylon clamp engaging the edges of the wafer. The wafer is then given a known clean-up drift. The ribs 2 and 3 are contacted by applying an In-Ga eutectic to the surfaces and pressing on to each face a flexible insulating base, e.g. of fibreglass or plastics material, carrying goldplated contact strips tinned with indium. The In-Ga euteetic alloys to the P-type ribs 3 to provide a low-resistance P-type surface layer. The process steps are controlled so that the sets of grooves 4, 5 intersect the NI and PI junctions respectively, to form an array of PIN diodes with co-ordinate connections. A gamma-ray camera. Fig. 2 (not shown), comprises a PIN diode array mounted with its lower face ribs (3) in thermal contact with a. plate (13) cooled by liquid nitrogen. A bias supply is connected via resistors. (8, 9) to the ribs (2, 3) so that the diodes are reverse biased. A gamma-ray source is viewed through a parallel hole collimator (7) the holes of which are aligned with the diodes of the array. Incidence of a gamma ray on a diode produces pulses at those electrodes. connected to the two ribs the intersection of which defines the diode. These output pulses are amplified and applied to a logic circuit which provides an output indicating the position of the point of the array on which the gamma ray impinged.
